Usage:
  $0 [<version=0.0.0.0>] [<configuration=release>] [<distro-platform-override>]

Versions must be complete four part idenfitiers valid for use on a .NET assembly.

Valid configurations are:
  debug
  release

The OS distribution and version will be detected automatically unless it is
overriden as the last argument. This script expects to find libjs1.[so|dylib]
in the src/libs/x64/distroname-distroversion/ directory, built using the scripts
in the scripts/build-js1/ directory. Note that overriding this may result in
crashes using Event Store.

*The only supported Linux for production use at the moment is Ubuntu 14.04 LTS.*
However, since several people have asked for builds compatible with Amazon Linux
in particular, we have included a pre-built version of libjs1.so which will
link to the correct version of libc on Amazon Linux 2015.03.

Currently the supported versions without needing to build libjs1 from source are:
  ubuntu-14.04              (Ubuntu Trusty)
  amazon-2015.03            (Amazon Linux 2015.03)
